Ingredients for canned diced potatoes
Five simple ingredients transform canned potatoes into a crispy, restaurant-quality side dish.
| Ingredient | Amount | Notes |
|---|---|---|
| Canned Diced Potatoes 🥔 | 2 cups | Drained and thoroughly dried |
| Extra-Virgin Olive Oil 🫒 | 2 tbsp | High-quality, fruity variety |
| Garlic Powder 🧄 | 1 tbsp | Freshly ground preferred |
| Dried Rosemary 🌿 | 1 tsp | Crushed between fingers |
| Dried Thyme 🍃 | 1 tsp | Or substitute dried oregano |
| Diamond Crystal Kosher Salt 🧂 | ½ tsp | Adjust to taste |
| Fresh Parsley 🌿 | ¼ cup | Chopped, for garnish (optional) |
| Parmesan Cheese 🧀 | ¼ cup | Freshly grated, for garnish (optional) |
The potatoes are the star here—Libby's or Del Monte are my go-tos, but any canned diced potatoes work. Drain them well, then spread them on a paper towel to dry completely. This step is non-negotiable for crispy edges. Whole Foods or Trader Joe's carry high-quality canned potatoes if you want to splurge. For the olive oil, California avocado oil works too if you prefer a neutral flavor. The garlic powder should smell fresh—if it's dusty, toss it and grab a new jar. Fresh herbs like rosemary and thyme elevate the flavor, but dried blends work in a pinch (just double the amount).
No garlic powder? Fresh garlic minced and toasted in oil adds depth. Dried herbs too strong? Mix equal parts dried rosemary and thyme for balance. Short on time? Pre-made Italian seasoning works, but it’s less aromatic. The optional parsley and Parmesan add brightness—skip them if you’re keeping it simple. For extra crispiness, toss the potatoes with an additional 1 tbsp olive oil after seasoning. And if you’re meal prepping, roast a second batch for leftovers—they reheat beautifully.
Roasted potatoes keep for 3-4 days in the fridge, but they’re best enjoyed fresh. Store in an airtight container to maintain crispiness. For meal prep, portion into containers with a sprinkle of Parmesan on top—it keeps the potatoes from getting soggy. If reheating, pop them in the oven at 400°F for 5-10 minutes to restore that golden crunch. Freezing isn’t recommended—they lose texture, but you can freeze the seasoned potatoes (unroasted) for up to 1 month if you’re planning ahead.

Step-by-step instructions for one-pan garlic-herb roast with crispy edges
Here's how to transform canned diced potatoes into a restaurant-worthy side dish with irresistible texture and flavor.
Prepare the Potatoes for Maximum Crispiness
Drain the 2 cups canned diced potatoes thoroughly and transfer them to a clean kitchen towel. Press the towel against the potatoes to remove every last bit of moisture—this is absolutely critical for achieving crispy edges. Wet potatoes will steam instead of brown. I like to do this over the sink so any excess water can drain away completely.
Once the potatoes are completely dry, spread them out in a single layer on a baking sheet and let them air-dry for an additional 10 minutes. This extra step ensures you'll get that perfect balance of tender centers and crispy exteriors. The potatoes should feel dry to the touch with no visible moisture when you handle them.
Season and Toss with Olive Oil
In a large bowl, combine the 2 cups dried potatoes with the 2 tablespoons extra-virgin olive oil. Drizzle the oil over the potatoes and use your hands to gently toss them until they're evenly coated. This creates a thin, flavorful barrier that will crisp beautifully in the oven.
Next, add the 1 tablespoon garlic powder, 1 teaspoon dried rosemary, 1 teaspoon dried thyme, and 0.5 teaspoon diamond crystal kosher salt. Work the seasonings into the potatoes thoroughly, pressing them gently between your fingers so they adhere to each surface. The herbs should be evenly distributed throughout the mixture for consistent flavor in every bite.
Roast Until Golden and Crispy
Preheat your oven to 425°F and position a rack in the middle position. Spread the seasoned potatoes evenly on a single large baking sheet, leaving about 1 inch between each piece to allow for proper browning. Don't crowd the pan—this is what creates those beautiful crispy edges we're after.
Roast for 25-30 minutes, stirring once halfway through the cooking time. You'll know they're ready when the edges are deep golden brown and the potatoes have developed a crispy texture. The centers should still feel tender when pierced with a fork—this indicates they've cooked through without drying out. If any pieces aren't browned enough, return them to the oven for an additional 5 minutes.
Finish with Fresh Herbs and Cheese
Remove the potatoes from the oven and let them cool for 2-3 minutes. This brief resting period allows the flavors to meld slightly and prevents the crispy edges from becoming soggy when you add the finishing touches. While they're cooling, chop the 0.25 cup fresh parsley and grate the 0.25 cup parmesan cheese.
Gently toss the warm potatoes with the chopped parsley and grated parmesan, being careful not to break up the crispy edges. The parsley adds a bright, fresh contrast to the earthy garlic-herb flavors, while the parmesan adds a salty, umami depth. Serve immediately while the edges are still crispy and the potatoes are warm throughout. This dish pairs beautifully with grilled meats or fresh salads.
Pro Tips For Making Canned Diced Potatoes
- Drain. Then Rinse.: Canned diced potatoes hold liquid like a sponge—skip rinsing, and your dish will turn into a watery stew. Pop them in a colander, run cold water over them for 10 seconds, and shake off the excess. Yes, even if the can says "ready to eat."
- Toast the Herbs First: Crush the dried rosemary and thyme between your palms before adding them to the oil. This releases their oils and aroma instantly—no more waiting for them to bloom while the potatoes sit. I used to toss them in whole, and it took three times as long to smell like a proper meal.
- Low and Slow for Even Heat: Crank the pan to medium-low heat after the initial sear. High heat burns the potatoes before the oil renders, leaving you with a bitter, uneven mess. I learned this the hard way—now I keep the heat steady and let the oil work its magic.
- Finish with a Splash of Water: If the potatoes start sticking or look dry after 5 minutes, add 1-2 tablespoons of water. The steam helps distribute the oil and herbs evenly, giving you crispy edges without burning. Sounds weird, but it works—your future self will notice the difference.

Frequently asked questions
Why do canned diced potatoes need to dry completely before roasting?
Drying the potatoes removes excess moisture that would cause them to steam instead of crisp. The towel method ensures even drying, while air-drying for 10 minutes guarantees that crispy texture we all love. Wet potatoes won't brown properly and will turn out soggy.
Can I use canned diced potatoes in a slow cooker instead of roasting?
For a slow-cooked version, combine 2 cups drained potatoes with 1 cup chicken broth, 1 tbsp olive oil, and your favorite seasonings. Cook on low for 4-5 hours until tender, then finish with a broil for 5 minutes to crisp the edges. This works great for casseroles or hearty sides.
What's the best way to reheat leftover roasted canned potatoes?
Reheat in a single layer on a baking sheet at 400°F for 5-10 minutes to restore crispiness. Microwaving will make them soggy. For extra flavor, add a splash of water or broth to the pan before reheating. Store in an airtight container for up to 4 days.
Are canned diced potatoes good for meal prep?
Yes! Roast a batch ahead and store in portions with a sprinkle of parmesan on top to maintain crispiness. They reheat beautifully and keep for 3-4 days in the fridge. For longer storage, freeze the seasoned potatoes (unroasted) for up to 1 month. Just roast from frozen, adding 5-10 extra minutes.
What if my roasted potatoes aren't crispy?
Check for excess moisture—they need to be bone-dry before roasting. If they're still wet, pat them thoroughly and spread them out to air-dry longer. Also ensure you're not overcrowding the pan, which traps steam. For extra crispiness, toss with an additional 1 tbsp olive oil after seasoning.
